Author's Note: Hey everyone thanks for all of the awesome reviews on the last chapter and wow I guess I shouldn't have forgotten X-23 on the first vote. She seems to be a very popular choice. So here is the next chapter and no the pairing isn't in here yet. Enjoy and don't forget to Review! When reviewing you can always let me know if you want some specific thing to happen and I'll think on it and see if I can put it in. Thanks!

Just realized I forgot to put the lines in where I had them. This is the repost with the proper lines. No change in the chapters plot.

Kisame extended his sword, pointing it at Naruto.

"So," he said, "What's it gonna be?"

"Over my dead body!" Naruto snapped.

"That can be arranged, eventually," Kisame laughed gleefully.

Naruto shouted, "Multi shadow clone jutsu!"

The shadow clones attacked the two Akatsuki attempting to get past either of their guards. After they had both taken out the clones they turned back to the group who had been unable to get past either ninja.

Logan unsheathed his claws charging Itachi being careful to keep his eyes on the ninja's hands and feet. Slashing at Itachi he came away with black cloth as he dodged the blades.

Gamakichi stayed in between trying to stay out of both battles as well as keep Charles safe from stray blades.

Kisame whirled the blade scraping the walls around them and striking at the clones finishing off several in a stroke of his sword. Naruto and one of his clones created a Rasengan in his hand. It was ready, the clone disappeared and he charged inside of Kisame's defense, striking him in the gut. Kisame was thrown back by the jutsu and into the wall down the way.

"Gamakichi! Logan! Down this way!" Naruto called.

Gamakichi came down the hall and passed Naruto. Logan charged Itachi and threw him back as hard as he could. Logan left Itachi getting up and followed Naruto and Gamakichi down the hallway.

"Follow me," Logan commanded and charged into the lead. He led them down the hall to the right before Kisame's slumped body.

"We need to get out of here and now!" Charles cried from Gamakichi's back.

Logan yelled back, "Working on it Chuck. Where's Storm and Beast?"

I'm calling them now, Charles said.

"You guys get out of here," Naruto said stopping.

"Naruto! You're the one they're after and the one we have to make sure they don't get a hold of," Gamakichi exclaimed.

"Exactly, that means if you all get away then I can use the Kyuubi's power to stop them."

Naruto there is a barrier still in the way!

Then take it down. I need to use the nine-tails power to win this fight. Don't worry I'll be okay and if not Gamakichi can head them off by going back to Konoha and warning the Hokage of what's happened. We already know the whereabouts of their hideout; it wouldn't be hard for them to find them or me.

Naruto don't throw your life away like this. What about your friends? Charles pleaded.

Either take it down or I'll fight without the extra chakra and the Nine-tails help.

Very well, give me a minute. He went inside Naruto to the sealed gateway where the fox waited behind his bars and the mental barrier. Charles removed the barrier and startled when he heard Naruto behind him.

Naruto stopped next to him and nodded his thanks, turning his attention back to the sealed gates he asked, Will you cooperate with me and lend me your strength?

The fox came forward showing its face only, Yes I will cooperate and lend you my strength, only because if you die I go with you. I will fight alongside you this time.

Thank you. Naruto turned back to Charles, Now get out of here. I'll either make it with his help or I won't. You guys don't know how to fight alongside a chakra user or for that matter one that might go out of control. I don't want to hurt anyone and I've already done so twice while in the Kyuubi state. Please make sure all three of you get out of here.

I will honor that wish, Charles said and left Naruto's mind.

When he came back to Gamakichi had already taken him and Logan away from Naruto. He began to worry when he saw the red energy cloaking Naruto.

"I thought you placed a barrier in him, Chuck."

"I did. I took it down at Naruto's request and the Kyuubi has agreed to fight alongside Naruto to aid him," he explained.

"The Kyuubi did what?" Gamakichi exclaimed.

"Just as I said, he agreed to fight alongside Naruto in the fight. Why what's wrong?"

"Well, see, everyone thought that any host that contained the Kyuubi would never be able to control it because of its enormous amounts of chakra that would be contained, not to mention the hatred the Fox had towards ninjas. So the fact that the Kyuubi is now willingly fighting alongside its host is incredible. Although that also means we should get away from here. All the power from that chakra can have some devastating results," Gamakichi explained.

Logan huffed in agreement. "Let's get out of here then and regroup with the rest of the X-Men."

"I agree Logan."

The three moved away from the mansion with Storm and Hank following close after them.

You ready boy?

I'm ready. You?

I'm just the power source here, remember?

No, you're more than that.

What's that supposed to mean?

You're a comrade fighting with me to win this battle.

Don't push it.

Heh… Here they come. Does the Mangekyo sharingan affect you?

Yes, so be careful.

I will.

They attacked with red chakra pouring out of their skin. They attacked and dodged, attacked and dodged, creating an image of many mini foxes attacking from all directions. A fourth tail grew into place alongside the three other tails. Kisame was blocking the attacks using his sword which slowly sucked the chakra out of the cloak and Itachi tried to meet his eyes to use the sharingan. The only thing he knew to ever take control of the Kyuubi. The only way that Madara was ever able to stage the attack of the Nine-tails on Konoha.

"Itachi, what are you doing over there? Haven't you made eye contact yet?"

Ignoring him Itachi closed his eyes and summoned up the power of the Mangekyo, Amaterasu. He opened his eyes tearing streaks of blood as he summoned the power forth to light anything in his line of sight on fire. It caught the Jinchuuriki as he passed at neck breaking speed in front of him.

In pain the Jinchuuriki stopped and writhed out of instinct to put out the fire. Waiting for Kisame to be close enough to knock the host out he put out the flames. Kisame slashed down with his sword swiping away chakra. He placed the sword against Naruto sucking away all the chakra that created the cloak and more when chakra began to take its place to form a new cloak.

He smirked, "You just don't know when to give up do you?"

"That's okay, since I don't know the meaning of giving up," Naruto countered.

"Too bad, we could've been done by now, but of course, where's the fun in that?" Kisame smiled.

Naruto growled and slashed at the sword swiping it away from him. He quickly pushed off the ground to land on the opposite side of the room from Kisame. Kisame smiled excitedly, anticipating the fun fight he was going to have.

Well what are you gonna do? I'm not going to allow you to let him steal all my chakra, ya got that?

Yeah I get it. I wasn't planning to allow him to steal the chakra in the first place, so don't worry and could you give me some more power? I'm not going to win like this unless we're both going at it with full power.

You're not afraid that I might try and take over? This would be the perfect chance for me. If you're okay with that possibility then sure I'll give you some more.

I trust you. Besides we agreed to work together, remember?

Heh, and you don't think I would just abandon you first thing? Okay. The Kyuubi fed the power through to Naruto bringing out the seven tails in total before stopping.

Hey, that's only seven tails…

That should be all you need if not I'll give you the last two.

Fine.

Naruto attacked once more…

Xavier Institute: The Back of the Mansion

Kitty phased them through the last wall out into the bright sun filled air. They all panted for air after being in the water for so long.

"Where's the Professor and Logan?" Bobby asked.

"Ah think they went with Naruto and that oversized Frog," Rogue said.

They all turned to look at the mansion as a resounding crash was heard faintly by the group.

"Ah think the battle has already started," Rogue pointed out.

"Vell how do ve fight against ninjas?" Kurt asked looking around at the group, "Anybody know?"

They all shook their heads in puzzled expressions.

"I think we have to learn as we go on this one," Scott said.

Jean nodded, "I agree, we've never had to fight ninjas before so none of us knows anything, not even the first thing there is to being a ninja."

"What are we waiting for then." Bobby suggested, "The sooner we find out the better… Right?"

They all nodded in agreement and charged around the building on both sides and in Kurts case over. What they found on the other side wasn't what they expected to see.

The front doors and 20 ft. around them were blown into non existence with a red figure getting back up on all four limbs in front of the fountain that was now flooding water onto the pathway. A man in a black coat with red clouds was slowly walking out with a large club looking thing resting on his shoulder. Some of the bandages were ripped revealing purple scales that were filed to points.

X-Men! Where are you? The professor called out.

We came out of the Institute from the back and we're on either side of the building, Kitty replied.

Kurt added, I'm on the roof looking down on the battle.

Good, I'm glad you're all safe and made it out alright. Regroup in front of the garage. Logan and I are already there.

Roger that, Scott answered.

Everyone headed for the garage skirting the battle that was underway.

Naruto felt stone give way from behind him as he was kicked into the fountain. Water flowed out over him drenching his clothes. He picked himself back up and stood at the ready on all fours staring Kisame down as he approached him.

Now would be a good time!

Sure, sure. Would you give me a break it's a bit of a strain to give out this much power to a human body. Are you sure you can you control all that power?

Yes, just give it to me now. We need to finish this!

Suit yourself.

The Kyuubi drained the last of his chakra reserves forming an eighth tail on Naruto…and a ninth tail to finish the set. Naruto shivered with the power, controlling it with all of his willpower. He shifted from foot to foot and hand to hand spreading the power evenly along his entire body. He pushed off from the ground leaving the cement caved in and pounced on Kisame swiping claws into his body creating large, deep cuts and biting whatever flesh was visible, mainly the neck, until Kisame reacted and he jumped off again.

Kisame looked down and cursed. He ran a hand on his neck where some bite marks had punctured the skin, blood smearing onto his hand when he looked at it.

"Damn you! You're not getting another chance like that again," Kisame shouted in anger.

Naruto grimaced, he'd only ever fought the chuckling Kisame and he didn't know how the Akatsuki's manner would change when he was pissed at his opponent. Kisame threw his sword with lightening fast speed and caught Naruto's left leg as he dodged.

Naruto flipped through the air landing with a crash, rolling to lessen the impact. His leg hurt, but then again his entire body was suffering from the chakra flowing around him creating the fox shape. Ignoring the pain he balanced himself back on his feet and focused on his attacker waiting for his next move.

Kisame charged him his sword flying back to him as he came, Naruto waited until the last minute, ducking under the attack he dived back towards the fountain rolling upon landing and gaining his feet he spun around to face Kisame.

What are you doing? Attack him already!

I need to separate him from his sword permanently somehow. Haven't you noticed that sword drains our energy every time it hits us?

Yes and that's exactly why you need to kill him now!

Will you give me a chance!

NO! If I'm going to deal with having a stupid human for a host then at least get rid of our adversaries quickly so I don't have to mix my chakra with yours for long.

What happened to willing cooperation?

Just get this fight over with!

Alright how about you fight, he offered.

The Kyuubi looked at him confused, You really are going to trust me on this one aren't you.

Like I said before we're comrades fighting side by side.

… All right.

Naruto thought to himself, Please don't let me be wrong. No, I have to trust him in order to do this.

Naruto walked up to the bars and placed his hand inside to rest on the Fox's paw sitting there placing his life in the tailed-beasts hands, something he never thought he would do.

Author's Note: Well there you have it. This chapter was bit violent at times and I think I stayed within the limits of the rating. Please review and let me know how I did. Ask any questions you like, I'll answer them if it doesn't spoil anything.
